M. V. B. BUELL, OF BUFFALO, NEW YORK.

VAPOR-LAMP.

Specification of Letters :Patent No. 28,063, dated May 1, 1860.

To all whom it may concern:

Be it known that I, M. V. B. BUELL, of Buffalo, in the county of Erieand State of New York, have invented a new and Improved Lamp; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawing,making a part of this specification, said drawing being a side sectionalview of a lamp constructed according to my invention.

This invention relates to certain improvements in that class of lampsgenerallyv known as vapor lamps, those in which the burning fiuid isvolatilized and gasiiied in the lamp previous to burning.

The object of the invention is to avoid the accidents attending the useof this class of lamps.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents a stand which is silnply a vertical rod ci attached to asuitable base B is a receiver or font which contains the burning fluid.This receiver or font may be of any proper shape and to its lower part ahorizontal tube C is attached said tube communicating with the interiorof the receiver or font and having a spherical chamber c connected withit through which chamber a tube or socket l passes. The chamber c doesnot communicate with the interior of the socket, but merely forms aproper support or bearing for it and permits the tube C to projectbeyond the rod a on which the socket d is fitted and allow-ed to slidefreely, the socket being secured at any desired point on the rod by aset screw e. The outer end of the tube C is screwed into a cock D havinga curved body, its outer end curving upward and having a vertical burnerE screwed into it. The burner E extends a trifle above the receiver orfont B, as shown clearly in the drawing. The burner is slotted downconsiderably below its upper end, say fve-eighths of an inch, as shownat f, or holes may be employed instead of the slot.

The operation is as follows: The receiver or font B being filled withburning fluid, and the cock D opened the fluid passes from the receiveror font through tube C, and into the vase of the burner E, which issupplied with a wick F, the supply of fluid to the burner beingregulated by the cock D.

In order to light the lamp a match or a piece of burning paper is heldfor a few seconds to the top of the burner, until the vapor isgenerated. The vapor ignites, and the fluid is then volatilized by theheat of the illuminating flame, no auxiliary flame being required norany heater. This result is due to the depth of the slot f orperforations whichever may be used the depth of the slot causes thesides of the burner to be heated as well as the top, and theilluminating flame is thereby made to generate its own gas.

By having the burner E, separated from the receiver or font B, thedanger of explosion by a pressure of gas therein is avoided as a greatvolume of fluid cannot be volatilized, as it is not in close proximityto the flame the fluid therefore is only volatilized as it is burned. Byhaving the tube O horizontal or approximating to such position, and theburner extending upward above it, the burner cannot overflow when thecock is fully open and the receiver or font full, a contingency which isliable to occur in those lamps which have their receivers higher thantheir burners.

W'hat I claim as my invention and desire to secure by Letters Patent is-Having the burner E, connected to the receiver or font B by a tube C, sothat the top of the burner will extend a little above the highest levelof the fluid in the receiver or font B for the purpose specified.
